2. BACKGROUND

According to the latest American Cancer Society's annual statisticalreport, released in January 2005, cancer has edged out heart disease asthe leading cause of death in Americans under age 85. In 2002, the mostrecent year for which information is available, 476,009 Americans under85 died of cancer compared with 450,637 who died of heart disease (thoseunder 85 comprise 98.4 percent of the US population). Protein tyrosinekinases (PTK), which historically represented the majority of firstdiscovered oncogenes, remain today one of the most important classes ofoncology drug targets.

Protein kinases are enzymes which covalently modify proteins andpeptides by the attachment of a phosphate group to one or more sites onthe protein or peptide (for example, PTK phosphorylate tyrosine groups).The measurement of protein kinase activity is important since studieshave shown that these enzymes are key regulators of many cell functions.

Over 500 protein kinases have been identified in the human genome(“kinome”) (Manning et al. (2002) Science. 298:1912). Based on therecent advances in deciphering the human genome, the family of human PTKconsists of approximately 90 members (Blume-Jensen and Hunter (2001)Nature, 411: 355-365; Robinson et al. (2000) Oncogene 19:5548-5557).This family can be divided in two major groups—receptor tyrosine kinases(RTK) and cytoplasmic (or non-receptor) tyrosine kinases (CTK)—andapproximately 30 subfamilies based on structural similarity (see, e.g.,Bolen et al. (1992) FASEB J. 6:3403-3409 (1992); Ullrich andSchlessinger (1990) Cell 61:203-212; Ihle (1995) Sem. Immunol.7:247-254. PTKs are involved in regulation of many cellular processes,such as cell proliferation, survival and apoptosis. Enhanced activity ofPTKs has been implicated in a variety of malignant and nonmalignantproliferative diseases. In addition, PTKs play a central role in theregulation of cells of the immune system. PTK inhibitors can thus impacta wide variety of oncologic and immunologic disorders. Such disordersmay be ameliorated by selective inhibition of a certain receptor ornon-receptor PTK, such as LCK, or due to the homology among PTK classes,by inhibition of more than one PTK by an inhibitor.

In some forms of cancer, a PTK mutation or structural alteration canincrease the ability to proliferate, and thus, provides an advantageover surrounding cells. PTK of growth factor receptors, for instance,have been shown to be involved in the transformation of normal tocancerous cells (see, e.g., Rao (1996) Curr. Opin. Oncol. 8:516-524).PTK also play a role in the regulation of apoptosis or programmed celldeath (see, e.g., Anderson (1997) Microbiol. Rev. 61:33). By activationof PTK, apoptosis mechanisms can be shut off and the elimination ofcancerous cells is prevented. Thus, PTK exert their oncogenic effectsvia a number of mechanisms such as driving proliferation and cellmotility and invasion. These PTK include HER2, BCR-ABL, SRC, and IGF1R.

There are many ways that a PTK can become oncogenic. For example,mutations (such as gain-of-function mutations) or small deletions in RTKand/or CTK are known to be associated with several malignancies (e.g.,KIT/SCFR, EGFR/ERBB1, CSF-1R, FGFR1, FGFR3, HGFR, RET). Additionally,overexpression of certain types of PTK resulting, for example, from geneamplification has been shown to be associated with several commoncancers in humans (e.g., EGFR/ERBB1, ERBB2/HER2/NEU, ERBB3/HER3,ERBB4/HER4, CSF-1R, PDGFR, FLK2/FLT3, FLT4NVEGFR3, FGFR1, FGFR2/K-SAM,FGFR4, HGFR, RON, EPHA2, PEHB2, EPHB4, AXL, TIE/TIE1). For a review ofoncogenic kinase signaling, and mutated kinase genes that may be used inthe systems and methods provided herein, see Blume-Jensen and Hunter(2001) Nature 411:355; Tibes et al (2005) Annu. Rev. Pharmacol. Toxicol.45:357; Gschwind (2004) Nature Reviews 4:361; Paul and Mukhopadhay(2004) Int. J. Med. Sci (2004) 1:101.

The majority of PTKs are believed to be important drug targets,especially for anti-cancer therapy. Indeed, a very large proportion ofknown PTKs have been shown to be hyperactivated in cancer cells due tooverexpression or constitutively activating mutations and to directlydrive tumor growth. In addition, a subset of RTKs, such as vascularendothelial growth factor receptors (VEGFR), fibroblast growth factorreceptors (FGFR) and some ephrin receptor (EPH) family members, isinvolved in driving angiogenesis while others (e.g., Met and discoidindomain receptor (DDR)) promote cell motility and invasion (e.g.,metastasis).

The formation of new blood vessels, either from differentiatingendothelial cells during embryonic development (vasculogenesis) or frompre-existing vessels during adult life (angiogenesis), is an essentialfeature of organ development, reproduction, and wound healing in higherorganisms. Folkman and Shing, J. Biol. Chem., 267: 10931-10934 (1992);Reynolds et al., FASEB J., 6: 886-892 (1992); Risau et al., Development,102: 471-478 (1988). Angiogenesis is implicated in the pathogenesis of avariety of disorders, including, but not limited to, solid tumors,intraocular neovascular syndromes such as proliferative retinopathies orage-related macular degeneration (AMD), rheumatoid arthritis, andpsoriasis (Folkman et al., J. Biol. Chem. 267:10931-10934 (1992);Klagsbrun et al., Annu. Rev. Physiol. 53:217-239 (1991); and Garner A,“Vascular Diseases”. In: Pathobiology of ocular disease. A dynamicapproach. Garner A, Klintworth G K, Eds. 2nd Edition Marcel Dekker, NY,pp 1625-1710 (1994)). For example, vascularization allows tumor cells insolid tumors to acquire a growth advantage and proliferative freedom ascompared to normal cells. Accordingly, a correlation has been observedbetween microvessel density in tumors and patient survival with variouscancers and tumors (Weidner et al., N Engl J Med 324:1-6 (1991); Horaket al., Lancet 340:1120-1124 (1992); and Macchiarini et al., Lancet340:145-146 (1992)).

A number of RTK have been identified that govern discrete stages ofvascular development (Folkman et al., Cell, 87:1153-1155 (1996);Hanahan, D., Science, 277:48-50 (1997); Risau, W., Nature, 386:671-674(1997); Yancopoulos et al., Cell, 93:661-664 (1998)). For example,VEGFR2 (FLK1), a receptor for vascular endothelial growth factor (VEGF),mediates endothelial and hematopoietic precursor cell differentiation(Shalaby et al., Nature, 376:62-66 (1995); Carmeliet et al., Nature,380:435-439 (1996); Ferrara et al., Nature 380:439-442 (1996)). VEGFalso governs later stages of angiogenesis through ligation of VEGFR1(FLT1) (Fong et al., Nature, 376:66-70 (1995)). Mice that lack VEGFR1have disorganized vascular endothelium with ectopic occurrence ofendothelial cells from the earliest stages of vascular development,suggesting that VEGFR1 signaling is essential for the proper assembly ofendothelial sheets (Fong et al., supra). Another tyrosine kinasereceptor, TEK (TIE2) (Dumont et al., Genes Dev. 8:1897-1909 (1994); Satoet al., Nature, 376:70-74 (1995)) and its ligands ANG1 (Davis et al.,Cell 87:1161-1169 (1996); Suri et al., Cell 87:1171-1180 (1996)) andANG2 (Maisonpierre et al., Science 277:55-60 (1997)) are involved inassembly of non-endothelial vessel wall components. TIE (TIE1) isinvolved in maintaining endothelial integrity, and its inactivationresults in perinatal lethality due to edema and hemorrhage (Sato, etal., Nature 376:70-74 (1995)). The TEK pathway seems to be involved inmaturation steps and promotes interactions between the endothelium andsurrounding vessel wall components (Suri et al., supra; and Vikkula etal., Cell 87:1181-1190 (1996)).

The EPH tyrosine kinase subfamily appears to be the largest subfamily oftransmembrane RTK (Pasquale et al., Curr. Opin. Cell Biol. 9:608-615(1997); and Orioli and Klein, Trends in Genetics 13:354-359 (1997)).Ephrins and their EPH receptors govern proper cell migration andpositioning during neural development, presumably through modulatingintercellular repulsion (Pasquale, supra; Otioli and Klein, supra).Bidirectional signaling has been observed for some Ephrin-B/EPHBligand/receptor pairs (Holland et al., Nature 383:722-725 (1996); andBruckner et al., Science 275:1640-1643 (1997)). For example, Ephrin-A1and Ephrin-B1 have been proposed to have angiogenic properties (Pandeyet al., Science 268:567-569 (1995); and Stein et al., Genes Dev.12:667-678 (1998)). Ephrin-B2, a ligand for EPHB4 receptor, was recentlyreported to mark the arterial compartment during early angiogenesis, andmice that lack Ephrin-B2 showed severe anomalies in capillary bedformation (Wang et al., Cell 93: 741-753 (1998)).

It is known that some compounds possess an ability to inhibit a tyrosinekinase activity. In particular, WO 2004 discloses imidazole and pyridinderivatives as tyrosine kinase inhibitors.

Thus, modulating tyrosine kinase activity by chemical compoundsrepresents a rational, targeted approach to cancer therapy.Additionally, because tyrosine kinases have a number of other diversebiological functions, such as regulation of metabolism, celldifferentiation, inflammation, immune responses, and tissuemorphogenesis, kinases are attractive for drug development outsideoncology.

It is to be understood that compounds having the same molecular formulabut differing in the nature or sequence of bonding of their atoms or inthe arrangement of their atoms in space are termed “isomers”. Isomersthat differ in the arrangement of their atoms in space are termed“stereoisomers”.

Stereoisomers that are not mirror images of one another are termed“diastereomers” and those that are non-superimposable mirror images ofeach other are termed “enantiomers”. When a compound has an asymmetriccenter, for example, when it is bonded to four different groups, a pairof enantiomers is possible. An enantiomer can be characterized by theabsolute configuration of its asymmetric center and is designated (R) or(S) according to the rules of Cahn and Prelog (Cahn et al., 1966, Angew.Chem. 78:413-447, Angew. Chem., Int. Ed. Engl. 5:385-414 (errata: Angew.Chem., Int. Ed. Engl. 5:511); Prelog and Helmchen, 1982, Angew. Chem.94:614-631, Angew. Chem. Internat. Ed. Eng. 21:567-583; Mata and Lobo,1993, Tetrahedron:Asymmetry 4:657-668) or can be characterized by themanner in which the molecule rotates the plane of polarized light and isdesignated dextrorotatory or levorotatory (i.e., as (+)- or (−)-isomers,respectively). A chiral compound can exist as either individualenantiomer or as a mixture thereof. A mixture containing equalproportions of enantiomers is called a “racemic mixture”.

In certain embodiments, the compounds of this invention may possess oneor more asymmetric centers; such compounds can therefore be produced asthe individual (R)- or (S)-enantiomer or as a mixture thereof. Unlessindicated otherwise, for example by designation of stereochemistry atany position of a formula, the description or naming of a particularcompound in the specification and claims is intended to include bothindividual enantiomers and mixtures, racemic or otherwise, thereof.Methods for determination of stereochemistry and separation ofstereoisomers are well-known in the art. In particular embodiments, thepresent invention provides the stereoisomers of the compounds depictedherein upon use of stereoisomerically pure intermediates in theirsynthesis, such as pure enantiomers, or diastereomers as buildingblocks, prepared by chiral synthesis methodologies, or resolution byformation of diastereomeric salts with chiral acid or base and theirseparation, or separation by means of chromatography, including usingchiral stationary phase. The racemic, or diastereomeric mixtures ofembodiments (compounds) in this invention can also be separated by meansof chromatography, including chiral stationary phase chromatography.

In certain embodiments, the compounds of the invention are“stereochemically pure.” A stereochemically pure compound has a level ofstereochemical purity that would be recognized as “pure” by those ofskill in the art. Of course, this level of purity will be less than100%. In certain embodiments, “stereochemically pure” designates acompound that is substantially free of alternate isomers. In particularembodiments, the compound is 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%,97%, 98%, 99%, 99.5% or 99.9% free of other isomers.

As used herein, the term “effective amount” refers to the amount of acompound of the invention which is sufficient to reduce or amelioratethe severity, duration of a disorder, cause regression of a disorder,prevent the recurrence, development, or onset of one or more symptomsassociated with a disorder, or enhance or improve the prophylactic ortherapeutic effect(s) of another therapy.

As used herein, the term “in combination” refers to the use of more thanone therapies. The use of the term “in combination” does not restrictthe order in which therapies (e.g., prophylactic and/or therapeuticagents) are administered to a subject with a disorder. A first therapycan be administered prior to (e.g., 5 minutes, 15 minutes, 30 minutes,45 minutes, 1 hour, 2 hours, 4 hours, 6 hours, 12 hours, 24 hours, 48hours, 72 hours, 96 hours, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6weeks, 8 weeks, or 12 weeks before), concomitantly with, or subsequentto (e.g., 5 minutes, 15 minutes, 30 minutes, 45 minutes, 1 hour, 2hours, 4 hours, 6 hours, 12 hours, 24 hours, 48 hours, 72 hours, 96hours, 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks, 6 weeks, 8 weeks, or12 weeks after) the administration of a second therapy to a subject witha disorder.

As used herein, the terms “prophylactic agent” and “prophylactic agents”as used refer to any agent(s) which can be used in the prevention of adisorder or one or more symptoms thereof. In certain embodiments, theterm “prophylactic agent” refers to a compound of the invention. Incertain other embodiments, the term “prophylactic agent” does not refera compound of the invention. In certain embodiments, a prophylacticagent is an agent which is known to be useful for, or has been or iscurrently being used to the prevent or impede the onset, development,progression and/or severity of a disorder. Prophylactic agents may becharacterized as different agents based upon one or more effects thatthe agents have in vitro and/or in vivo. For example, an anti-angiogenicagent may also be characterized as an immunomodulatory agent.

As used herein, the terms “prevent,” “preventing” and “prevention” referto the prevention of the recurrence, onset, or development of one ormore symptoms of a disorder in a subject resulting from theadministration of a therapy, or the administration of a combination oftherapies.

As used herein, the phrase “prophylactically effective amount” refers tothe amount of a therapy which is sufficient to result in the preventionof the development, recurrence or onset of one or more symptomsassociated with a disorder, or to enhance or improve the prophylacticeffect(s) of another therapy.

As used herein, the term “synergistic” refers to a combination of acompound of the invention and another therapy which has been or iscurrently being used to prevent, manage or treat a disorder, which ismore effective than the additive effects of the therapies. A synergisticeffect of a combination of therapies permits the use of lower dosages ofone or more of the therapies and/or less frequent administration of saidtherapies to a subject with a disorder. The ability to utilize lowerdosages of a therapy and/or to administer said therapy less frequentlyreduces the toxicity associated with the administration of said therapyto a subject without reducing the efficacy of said therapy in theprevention, management or treatment of a disorder. In addition, asynergistic effect can result in improved efficacy of agents in theprevention, management or treatment of a disorder. Finally, asynergistic effect of a combination of therapies may avoid or reduceadverse or unwanted side effects associated with the use of eithertherapy alone.

As used herein, the terms “therapeutic agent” and “therapeutic agents”refer to any agent(s) which can be used in the treatment, management, oramelioration of a disorder or one or more symptoms thereof.

In certain embodiments, compounds of formula (1) are prepared accordingto the following procedures, according to scheme 1.

Scheme 1 describes the preparation of the tricycles. The startingdiamino phthalimides and/or diaminolactams B (and/or their derivatives)are available by the synthetic methodologies described below. The methodis general and is applicable to a variety of derivatives with differentgroups R¹, Y¹ and Y², as well as various X¹ through X⁶ and W¹ throughW⁶.

Condensations of the suitable aromatic, or heteroaromatic aldehydes (A,A′) with the diamino-heterocycles (B) give in the presence of air, or asuitable oxidant the desired substituted aromatic heterotricycles (C,C′). In the addition of exposure to air, use of palladium on charcoal,Raney nickel, or dehydrogenating agents, such as sulfur, Oxone^(R),ferric chloride, sodium bisulfite, benzoquinone, or its derivatives andthe like will also accomplish dehydrogenation of the initially formeddihydroderivatives to the aromatic heterotricycles (C, C′). Othermethods for cyclization of benzimidazole-type derivatives are known inthe art and can be utilized in the formation of the presentheterotricyclic compounds, by way of example, but not limited to:acylation of the diamines (B) with an activated form of the carboxylicacids (D, D′), such as acid chlorides, fluorides, imidazolides, DCC, orDIC and related adducts with the diamine (B), followed by formation ofthe imidazole ring in acidic, or basic conditions (e.g.: heating inacetic acid, or in alcoholic potassium, or sodium methoxide, or use ofPPA, or POCl3 in the presence of pyridine, or diisopropylethylamine, togive (C,C′). Alternatively, the 2-nitroamine (E) can be used for theacylation step, followed by reduction with titanium trichloride, orstannous chloride solution, followed by cyclization of the monoacyldiamine in acidic, or basic conditions (e.g.: heating in acetic acid, orin alcoholic potassium, or sodium methoxide, or use of PPA, or POCl3 inthe presence of pyridine, or diisopropylethylamine, to give (C,C′).Carboxylic acids (D,D′) are accessible by methods known in the art,including Kolbe synthesis, carboxylation of the corresponding lithiumcarbanions (preferably in a protected form, such as MOM ethers, ormethoxy derivatives, followed by deprotection with HCl, or BBr₃) withCO₂, or oxidation of the corresponding aldehydes (A,A′) with Ag₂O, orsodium chlorite/isobutylene, under standard conditions.

In certain embodiments, compounds of formula (1) are prepared accordingto the following procedures, according to schemes 2-20.

Description of a substituent as R and R′ means that it may be anychemically feasible substituent, including hydrogen.

Preparation of 4-bromo-3-cyano-2-methoxypyridine and4-iodo-3-cyano-2-methoxypyridine and the corresponding aldehydes

Thus, 2-chloro-3-cyanopyridine (A18) provided 2-methoxy-3-cyanopyridine(A19) upon treatment with sodium methoxide in methanol. Lithiation ofthe 2-methoxy-3-cyanopyridine (A19) with LDA gave the intermediatecarbanion derivative 4-lithio-2-methoxy-3-cyanopyridine (A21), whichupon treatment with hexachloroethane provided the4-chloro-2-methoxy-3-cyanopyridine (A20). Analogously, reaction withbromine provides the 4-bromo-2-methoxy-3-cyanopyridine (A22) andreaction with iodine provides the 4-iodo-2-methoxy-3-cyanopyridine(A23). All 4-halo-2-methoxy-3-cyanopyridines are highly valuableintermediates, especially for the synthesis of kinase inhibitors.Reduction of the 4-halo-2-methoxy-3-cyanopyridines, for example withDIBAL (diisobutylaluminum hydride) in solvents such as toluene,dichloromethane, or tetrahydrofuran at temperatures ranging from −80° C.to about 80° C., preferably at 20° C. provides after standard workup the4-halo-2-methoxypyridine-3-carboxaldehydes. The4-halo-2-methoxypyridine-3-carboxaldehydes are highly valuable syntheticintermediates. 4-chloro-2-methoxy-3-pyridinecarboxaldehyde (A9) wasprepared in this manner.

4.4 Compositions and Method of Administration

In certain aspects, provided herein are compositions comprising acompound or a stereoisomer, tautomer, salt, hydrate or prodrug providedherein. The compositions can be used, for example, in the methods of usedescribed herein.

In certain embodiments, a composition is a pharmaceutical composition ora single unit dosage form. Pharmaceutical compositions and single unitdosage forms comprise a prophylactically or therapeutically effectiveamount of one or more prophylactic or therapeutic agents (e.g., acompound of the invention, or other prophylactic or therapeutic agent),and a typically one or more pharmaceutically acceptable carriers orexcipients or diluents. In one non-limiting embodiment, the term“pharmaceutically acceptable” means approved by a regulatory agency ofthe Federal or a state government or listed in the U.S. Pharmacopeia orother generally recognized pharmacopeia for use in animals, and moreparticularly in humans. The term “carrier” refers to a diluent, adjuvant(e.g., Freund's adjuvant (complete and incomplete)), excipient, orvehicle with which the therapeutic is administered. Such pharmaceuticalcarriers can be sterile liquids, such as water and oils, including thoseof petroleum, animal, vegetable or synthetic origin, such as peanut oil,soybean oil, mineral oil, sesame oil and the like. Water is a particularcarrier when the pharmaceutical composition is administeredintravenously. Saline solutions and aqueous dextrose and glycerolsolutions can also be employed as liquid carriers, particularly forinjectable solutions. Examples of suitable pharmaceutical carriers aredescribed in “Remington's Pharmaceutical Sciences” by E. W. Martin.

In one embodiment, pharmaceutical compositions and dosage forms compriseone or more excipients. Suitable excipients are well-known to thoseskilled in the art of pharmacy, and non-limiting examples of suitableexcipients include starch, glucose, lactose, sucrose, gelatin, malt,rice, flour, chalk, silica gel, sodium stearate, glycerol monostearate,talc, sodium chloride, dried skim milk, glycerol, propylene, glycol,water, ethanol and the like. Whether a particular excipient is suitablefor incorporation into a pharmaceutical composition or dosage formdepends on a variety of factors well known in the art including, but notlimited to, the way in which the dosage form will be administered to apatient and the specific active ingredients in the dosage form. Thecomposition or single unit dosage form, if desired, can also containminor amounts of wetting or emulsifying agents, or pH buffering agents.

Lactose-free compositions of the invention can comprise excipients thatare well known in the art and are listed, for example, in the U.S.Pharmocopia (USP) SP (XXI)/NF (XVI). In general, lactose-freecompositions comprise an active ingredient, a binder/filler, and alubricant in pharmaceutically compatible and pharmaceutically acceptableamounts. Exemplary lactose-free dosage forms comprise an activeingredient, microcrystalline cellulose, pre-gelatinized starch, andmagnesium stearate.

Also provided are anhydrous pharmaceutical compositions and dosage formscomprising active ingredients, since water can facilitate thedegradation of some compounds. For example, the addition of water (e.g.,5%) is widely accepted in the pharmaceutical arts as a means ofsimulating long-term storage in order to determine characteristics suchas shelf-life or the stability of formulations over time. See, e.g.,Jens T. Carstensen, Drug Stability: Principles & Practice, 2d. Ed.,Marcel Dekker, NY, N.Y., 1995, pp. 379-80. In effect, water and heataccelerate the decomposition of some compounds. Thus, the effect ofwater on a formulation can be of great significance since moistureand/or humidity are commonly encountered during manufacture, handling,packaging, storage, shipment, and use of formulations.

Anhydrous pharmaceutical compositions and dosage forms of the inventioncan be prepared using anhydrous or low moisture containing ingredientsand low moisture or low humidity conditions. Pharmaceutical compositionsand dosage forms that comprise lactose and at least one activeingredient that comprises a primary or secondary amine are in certainembodiments anhydrous if substantial contact with moisture and/orhumidity during manufacturing, packaging, and/or storage is expected.

An anhydrous pharmaceutical composition can be prepared and stored suchthat its anhydrous nature is maintained. Accordingly, anhydrouscompositions are in certain embodiments packaged using materials knownto prevent exposure to water such that they can be included in suitableformulary kits. Examples of suitable packaging include, but are notlimited to, hermetically sealed foils, plastics, unit dose containers(e.g., vials), blister packs, and strip packs.

Further provided are pharmaceutical compositions and dosage forms thatcomprise one or more compounds that reduce the rate by which an activeingredient will decompose. Such compounds, which are referred to hereinas “stabilizers,” include, but are not limited to, antioxidants such asascorbic acid, pH buffers, or salt buffers.

The pharmaceutical compositions and single unit dosage forms can takethe form of solutions, suspensions, emulsion, tablets, pills, capsules,powders, sustained-release formulations and the like. Oral formulationcan include standard carriers such as pharmaceutical grades of mannitol,lactose, starch, magnesium stearate, sodium saccharine, cellulose,magnesium carbonate, etc. Such compositions and dosage forms willcontain a prophylactically or therapeutically effective amount of aprophylactic or therapeutic agent in certain embodiments in purifiedform, together with a suitable amount of carrier so as to provide theform for proper administration to the patient. The formulation shouldsuit the mode of administration. In certain embodiments, thepharmaceutical compositions or single unit dosage forms are sterile andin suitable form for administration to a subject, in certain embodimentsan animal subject, such as a mammalian subject, particularly a humansubject.

A pharmaceutical composition of the invention is formulated to becompatible with its intended route of administration. Examples of routesof administration include, but are not limited to, parenteral, e.g.,intravenous, intradermal, subcutaneous, intramuscular, subcutaneous,oral, buccal, sublingual, inhalation, intranasal, transdermal, topical,transmucosal, intra-tumoral, intra-synovial and rectal administration.In a specific embodiment, the composition is formulated in accordancewith routine procedures as a pharmaceutical composition adapted forintravenous, subcutaneous, intramuscular, oral, intranasal or topicaladministration to human beings. In an embodiment, a pharmaceuticalcomposition is formulated in accordance with routine procedures forsubcutaneous administration to human beings. Typically, compositions forintravenous administration are solutions in sterile isotonic aqueousbuffer. Where necessary, the composition may also include a solubilizingagent and a local anesthetic such as lignocamne to ease pain at the siteof the injection.

Examples of dosage forms include, but are not limited to: tablets;caplets; capsules, such as soft elastic gelatin capsules; cachets;troches; lozenges; dispersions; suppositories; ointments; cataplasms(poultices); pastes; powders; dressings; creams; plasters; solutions;patches; aerosols (e.g., nasal sprays or inhalers); gels; liquid dosageforms suitable for oral or mucosal administration to a patient,including suspensions (e.g., aqueous or non-aqueous liquid suspensions,oil-in-water emulsions, or a water-in-oil liquid emulsions), solutions,and elixirs; liquid dosage forms suitable for parenteral administrationto a patient; and sterile solids (e.g., crystalline or amorphous solids)that can be reconstituted to provide liquid dosage forms suitable forparenteral administration to a patient.

The composition, shape, and type of dosage forms of the invention willtypically vary depending on their use. For example, a dosage form usedin the acute treatment of inflammation or a related disorder may containlarger amounts of one or more of the active ingredients it comprisesthan a dosage form used in the chronic treatment of the same disease.Also, the therapeutically effective dosage form may vary among differenttypes of cancer. Similarly, a parenteral dosage form may contain smalleramounts of one or more of the active ingredients it comprises than anoral dosage form used to treat the same disease or disorder. These andother ways in which specific dosage forms encompassed by this inventionwill vary from one another will be readily apparent to those skilled inthe art. See, e.g., Remington's Pharmaceutical Sciences, 18th ed., MackPublishing, Easton Pa. (1990).

Generally, the ingredients of compositions of the invention are suppliedeither separately or mixed together in unit dosage form, for example, asa dry lyophilized powder or water free concentrate in a hermeticallysealed container such as an ampoule or sachette indicating the quantityof active agent. Where the composition is to be administered byinfusion, it can be dispensed with an infusion bottle containing sterilepharmaceutical grade water or saline. Where the composition isadministered by injection, an ampoule of sterile water for injection orsaline can be provided so that the ingredients may be mixed prior toadministration.

Typical dosage forms of the invention comprise a compound of theinvention, or a pharmaceutically acceptable salt, solvate or hydratethereof lie within the range of from about 0.1 mg to about 1000 mg perday. Particular dosage forms of the invention have about 0.1, 0.2, 0.3,0.4, 0.5, 1.0, 2.0, 2.5, 5.0, 10.0, 15.0, 20.0, 25.0, 50.0, 100, 200,250, 500 or 1000 mg of the compound.

4.4.1 Oral Dosage Forms

Pharmaceutical compositions that are suitable for oral administrationcan be presented as discrete dosage forms, such as, but are not limitedto, tablets (e.g., chewable tablets), caplets, capsules, and liquids(e.g., flavored syrups). Such dosage forms contain predetermined amountsof active ingredients, and may be prepared by methods of pharmacy wellknown to those skilled in the art. See generally, Remington'sPharmaceutical Sciences, 18th ed., Mack Publishing, Easton Pa. (1990).

In certain embodiments, the oral dosage forms are solid and preparedunder anhydrous conditions with anhydrous ingredients, as described indetail in the sections above. However, the scope of the inventionextends beyond anhydrous, solid oral dosage forms. As such, furtherforms are described herein.

Typical oral dosage forms of the invention are prepared by combining theactive ingredient(s) in an intimate admixture with at least oneexcipient according to conventional pharmaceutical compoundingtechniques. Excipients can take a wide variety of forms depending on theform of preparation desired for administration. For example, excipientssuitable for use in oral liquid or aerosol dosage forms include, but arenot limited to, water, glycols, oils, alcohols, flavoring agents,preservatives, and coloring agents. Examples of excipients suitable foruse in solid oral dosage forms (e.g., powders, tablets, capsules, andcaplets) include, but are not limited to, starches, sugars,micro-crystalline cellulose, diluents, granulating agents, lubricants,binders, and disintegrating agents.

Because of their ease of administration, tablets and capsules representthe most advantageous oral dosage unit forms, in which case solidexcipients are employed. If desired, tablets can be coated by standardaqueous or nonaqueous techniques. Such dosage forms can be prepared byany of the methods of pharmacy. In general, pharmaceutical compositionsand dosage forms are prepared by uniformly and intimately admixing theactive ingredients with liquid carriers, finely divided solid carriers,or both, and then shaping the product into the desired presentation ifnecessary.

For example, a tablet can be prepared by compression or molding.Compressed tablets can be prepared by compressing in a suitable machinethe active ingredients in a free-flowing form such as powder orgranules, optionally mixed with an excipient. Molded tablets can be madeby molding in a suitable machine a mixture of the powdered compoundmoistened with an inert liquid diluent.

Examples of excipients that can be used in oral dosage forms of theinvention include, but are not limited to, binders, fillers,disintegrants, and lubricants. Binders suitable for use inpharmaceutical compositions and dosage forms include, but are notlimited to, corn starch, potato starch, or other starches, gelatin,natural and synthetic gums such as acacia, sodium alginate, alginicacid, other alginates, powdered tragacanth, guar gum, cellulose and itsderivatives (e.g., ethyl cellulose, cellulose acetate, carboxymethylcellulose calcium, sodium carboxymethyl cellulose), polyvinylpyrrolidone, methyl cellulose, pre-gelatinized starch, hydroxypropylmethyl cellulose, (e.g., Nos. 2208, 2906, 2910), microcrystallinecellulose, and mixtures thereof.

Examples of fillers suitable for use in the pharmaceutical compositionsand dosage forms disclosed herein include, but are not limited to, talc,calcium carbonate (e.g., granules or powder), microcrystallinecellulose, powdered cellulose, dextrates, kaolin, mannitol, silicicacid, sorbitol, starch, pre-gelatinized starch, and mixtures thereof.The binder or filler in pharmaceutical compositions of the invention istypically present in from about 50 to about 99 weight percent of thepharmaceutical composition or dosage form.

Suitable forms of microcrystalline cellulose include, but are notlimited to, the materials sold as AVICEL-PH-101, AVICEL-PH-103 AVICELRC-581, AVICEL-PH-105 (available from FMC Corporation, American ViscoseDivision, Avicel Sales, Marcus Hook, PA), and mixtures thereof. Anspecific binder is a mixture of microcrystalline cellulose and sodiumcarboxymethyl cellulose sold as AVICEL RC-581. Suitable anhydrous or lowmoisture excipients or additives include AVICEL-PH-103™ and Starch 1500LM.

Disintegrants are used in the compositions of the invention to providetablets that disintegrate when exposed to an aqueous environment.Tablets that contain too much disintegrant may disintegrate in storage,while those that contain too little may not disintegrate at a desiredrate or under the desired conditions. Thus, a sufficient amount ofdisintegrant that is neither too much nor too little to detrimentallyalter the release of the active ingredients should be used to form solidoral dosage forms of the invention. The amount of disintegrant usedvaries based upon the type of formulation, and is readily discernible tothose of ordinary skill in the art. Typical pharmaceutical compositionscomprise from about 0.5 to about 15 weight percent of disintegrant,specifically from about 1 to about 5 weight percent of disintegrant.

Disintegrants that can be used in pharmaceutical compositions and dosageforms of the invention include, but are not limited to, agar-agar,alginic acid, calcium carbonate, microcrystalline cellulose,croscarmellose sodium, crospovidone, polacrilin potassium, sodium starchglycolate, potato or tapioca starch, pre-gelatinized starch, otherstarches, clays, other algins, other celluloses, gums, and mixturesthereof.

Lubricants that can be used in pharmaceutical compositions and dosageforms of the invention include, but are not limited to, calciumstearate, magnesium stearate, mineral oil, light mineral oil, glycerin,sorbitol, mannitol, polyethylene glycol, other glycols, stearic acid,sodium lauryl sulfate, talc, hydrogenated vegetable oil (e.g., peanutoil, cottonseed oil, sunflower oil, sesame oil, olive oil, corn oil, andsoybean oil), zinc stearate, ethyl oleate, ethyl laureate, agar, andmixtures thereof. Additional lubricants include, for example, a syloidsilica gel (AEROSIL 200, manufactured by W.R. Grace Co. of Baltimore,Md.), a coagulated aerosol of synthetic silica (marketed by Degussa Co.of Plano, Tex.), CAB-O-SIL (a pyrogenic silicon dioxide product sold byCabot Co. of Boston, Mass.), and mixtures thereof. If used at all,lubricants are typically used in an amount of less than about 1 weightpercent of the pharmaceutical compositions or dosage forms into whichthey are incorporated.

4.4.2 Controlled Release Dosage Forms

Active ingredients such as the compounds provided herein can beadministered by controlled release means or by delivery devices that arewell known to those of ordinary skill in the art. Examples include, butare not limited to, those described in U.S. Pat. Nos. 3,845,770;3,916,899; 3,536,809; 3,598,123; and 4,008,719, 5,674,533, 5,059,595,5,591,767, 5,120,548, 5,073,543, 5,639,476, 5,354,556, and 5,733,566,each of which is incorporated herein by reference. Such dosage forms canbe used to provide slow or controlled-release of one or more activeingredients using, for example, hydropropylmethyl cellulose, otherpolymer matrices, gels, permeable membranes, osmotic systems, multilayercoatings, microparticles, liposomes, microspheres, or a combinationthereof to provide the desired release profile in varying proportions.Suitable controlled-release formulations known to those of ordinaryskill in the art, including those described herein, can be readilyselected for use with the active ingredients of the invention. Theinvention thus encompasses single unit dosage forms suitable for oraladministration such as, but not limited to, tablets, capsules, gelcaps,and caplets that are adapted for controlled-release.

All controlled-release pharmaceutical products have a common goal ofimproving drug therapy over that achieved by their non-controlledcounterparts. Ideally, the use of an optimally designedcontrolled-release preparation in medical treatment is characterized bya minimum of drug substance being employed to cure or control thecondition in a minimum amount of time. Advantages of controlled-releaseformulations include extended activity of the drug, reduced dosagefrequency, and increased patient compliance. In addition,controlled-release formulations can be used to affect the time of onsetof action or other characteristics, such as blood levels of the drug,and can thus affect the occurrence of side (e.g., adverse) effects.

Most controlled-release formulations are designed to initially releasean amount of drug (active ingredient) that promptly produces the desiredtherapeutic effect, and gradually and continually release of otheramounts of drug to maintain this level of therapeutic or prophylacticeffect over an extended period of time. In order to maintain thisconstant level of drug in the body, the drug must be released from thedosage form at a rate that will replace the amount of drug beingmetabolized and excreted from the body. Controlled-release of an activeingredient can be stimulated by various conditions including, but notlimited to, pH, temperature, enzymes, water, or other physiologicalconditions or compounds.

4.4.3 Parenteral Dosage Forms

Parenteral dosage forms can be administered to patients by variousroutes including, but not limited to, subcutaneous, intravenous(including bolus injection), intramuscular, and intraarterial. Becausetheir administration typically bypasses patients' natural defensesagainst contaminants, parenteral dosage forms are in certain embodimentssterile or capable of being sterilized prior to administration to apatient.

Transdermal, topical, and mucosal dosage forms of the invention include,but are not limited to, ophthalmic solutions, sprays, aerosols, creams,lotions, ointments, gels, solutions, emulsions, suspensions, or otherforms known to one of skill in the art. See, e.g., Remington'sPharmaceutical Sciences, 16th and 18th eds., Mack Publishing, Easton Pa.(1980 & 1990); and Introduction to Pharmaceutical Dosage Forms, 4th ed.,Lea & Febiger, Philadelphia (1985). Dosage forms suitable for treatingmucosal tissues within the oral cavity can be formulated as mouthwashesor as oral gels. Further, transdermal dosage forms include “reservoirtype” or “matrix type” patches, which can be applied to the skin andworn for a specific period of time to permit the penetration of adesired amount of active ingredients.

Suitable excipients (e.g., carriers and diluents) and other materialsthat can be used to provide transdermal, topical, and mucosal dosageforms encompassed by this invention are well known to those skilled inthe pharmaceutical arts, and depend on the particular tissue to which agiven pharmaceutical composition or dosage form will be applied. Withthat fact in mind, typical excipients include, but are not limited to,water, acetone, ethanol, ethylene glycol, propylene glycol,butane-1,3-diol, isopropyl myristate, isopropyl palmitate, mineral oil,and mixtures thereof to form lotions, tinctures, creams, emulsions, gelsor ointments, which are non-toxic and pharmaceutically acceptable.Moisturizers or humectants can also be added to pharmaceuticalcompositions and dosage forms if desired. Examples of such additionalingredients are well known in the art. See, e.g., Remington'sPharmaceutical Sciences, 16th and 18th eds., Mack Publishing, Easton Pa.(1980 & 1990).

Depending on the specific tissue to be treated, additional componentsmay be used prior to, in conjunction with, or subsequent to treatmentwith active ingredients of the invention. For example, penetrationenhancers can be used to assist in delivering the active ingredients tothe tissue. Suitable penetration enhancers include, but are not limitedto: acetone; various alcohols such as ethanol, oleyl, andtetrahydrofuryl; alkyl sulfoxides such as dimethyl sulfoxide; dimethylacetamide; dimethyl formamide; polyethylene glycol; pyrrolidones such aspolyvinylpyrrolidone; Kollidon grades (Povidone, Polyvidone); urea; andvarious water-soluble or insoluble sugar esters such as Tween 80(polysorbate 80) and Span 60 (sorbitan monostearate).

The pH of a pharmaceutical composition or dosage form, or of the tissueto which the pharmaceutical composition or dosage form is applied, mayalso be adjusted to improve delivery of one or more active ingredients.Similarly, the polarity of a solvent carrier, its ionic strength, ortonicity can be adjusted to improve delivery. Compounds such asstearates can also be added to pharmaceutical compositions or dosageforms to advantageously alter the hydrophilicity or lipophilicity of oneor more active ingredients so as to improve delivery. In this regard,stearates can serve as a lipid vehicle for the formulation, as anemulsifying agent or surfactant, and as a delivery-enhancing orpenetration-enhancing agent. Different salts, hydrates or solvates ofthe active ingredients can be used to further adjust the properties ofthe resulting composition.

4.4.6 Biological Assays

The following assays can be employed in ascertaining the activity of asmall-molecule compound as an inhibitor of the catalytic kinase activityof various tyrosine kinases.

4.4.6.1 Kinase Assays

To determine inhibition of several tyrosine kinases, such as IGF1R,InsR, Alk, TrkA and Jak2, kinase assays are conducted using eitherKinase-Glo (Promega) or AlphaScreen (PerkinElmer) kinase assayplatforms. The Kinase-Glo Luminescent Kinase Assay is a homogeneousmethod for measuring kinase activity by determining the amount of ATPremaining after a kinase reaction. The luminescent signal isproportional to the amount of ATP and inversely proportional to theamount of kinase activity. Tyrosine kinase PT66 AlphaScreen Assay is ahigh-sensitivity homogeneous, anti-phosphotyrosine antibody-mediatedluminescent proximity method measuring, incorporation of phosphate insynthetic poly(Glu-Tyr) substrate. The kinase preparations used consistof purified recombinant, 6×His- or GST-tagged kinase domain fragments ofthe corresponding RTKs expressed in baculovirus system.

4.4.6.1.1 ELISA-Based Assay of IGF1 Receptor AutophosphorylationInhibition in Cells

In another embodiment, compounds that interact with the IGF1R kinasedomain are tested in a cell-based assay system. In accordance with thisembodiment, cells expressing a full-length IGF1 receptor or a fragmentthereof containing the IGF1R kinase domain, are contacted with acandidate or a control compound and the ability of the compound to blocktyrosine kinase activity of IGF1R within a cell is determined. Thisassay may be used to screen a single compound or a large library ofcandidate compounds. Typically, the cells or cell lines are of mammalianorigin and they can express the IGF1 receptor, or functional IGF1Rkinase domain fragment, endogenously or be genetically engineered toexpress the IGF1R, or functional fragment thereof. The ability of thecandidate compound to inhibit IGF1R kinase activity can be determined bymethods known to those skilled in the art. For example, the inhibitioncan be determined by ELISA-type assay or Western blot analysis with celllysates or immunoprecipitated IGF1R receptor using various anti-IGF1Rand anti-phosphotyrosine antibodies.

In general, cells expressing IGF1R are treated with modulators (i.e.,inhibitors or activators) of IGF1R kinase activity and cell lysates areproduced from these treated cells. IGF1Rs are isolated from the lysateby immunoprecipitation and analyzed for phosphotyrosine content.Alternatively, or in addition, cellular protein substratesphosphorylated by IGFR may be immunoprecipitated from the lysates andtheir degree of tyrosine phosphorylation determined.

4.4.6.2 Cell Proliferation Inhibition Assay

IGF1R and other tyrosine kinase inhibitors can inhibit the proliferationof certain cancer cell lines indicating their possible therapeuticutility for treating the corresponding cancer types. Cancer cell linesof interest and control normal lines, including CHO, HEK293, BA/F3, MM1,H929, COLO205, PC3, DU145, MCF7, Panc1, ACHN, Hep G2, H460, K562, TT,U87-G, CAOV-3, SK-MEL5, Karpas 299, are plated in white, clear-bottomed384-well cell culture plates at 2500-5000 cells per well and suppliedwith dilutions of tested compounds After a desired period of time(typically 3 days), the number of viable cells is quantitated by usingCell Titer-Glo Luminescent Cell Viability Assay (Promega), a cellproliferation assay system based on detection of total amount of ATPpresent as a measure of cell metabolic activity. The plated cells aremixed with the Cell Titer-Glo developing reagent and counted in aluminescence multiwell plate reader according to the standardmanufacturer's protocol to generate IC50 curves for cell proliferationinhibition.

4.4.6.3 Kinase Profiling

To determine inhibitory activity of the compounds against a panel oftyrosine and serine-threonine kinases, the commercial kinase panelprofiling service (Kinase Profiler, Upstate Biotechnologies) isutilized. This kinase inhibition profiling platform consists of standardradiometric kinase assays in filter binding format based on directmeasurements of radioactive phosphate incorporation in specific kinasesubstrates by scintillation counting.

6.3. Example 3 ELISA-based Assay of IGF1 Receptor AutophosphorylationInhibition in Cells

MCF7 human breast cancer cells expressing IGF1 receptor or an engineeredhuman fibroblast cell line NIH 3T3 overexpressing full-length IGF1R arean exemplary cellular models in which to perform such assays. Such cellsmay be maintained in DMEM medium supplemented with 10% fetal bovineserum (FBS), 4% L-glutamine, 1% antibiotic solution(penicillin-Streptomycin) in a humidified atmosphere of 95% air and 5%CO₂ at 37° C. Confluent cells in T175 cell culture flasks are incubatedovernight with serum-free DMEM medium. After the serum starvation step,the cells are detached and split into a standard 96-well cell cultureplate (one T175 flask per plate, 30 μl of cell suspension per platewell). Tested inhibitors from their 10 mM stock solutions in DMSO aresubsequently added at various concentrations in serum-free DMEM mediumfor 1 hour incubation at 37° C. in CO₂-incubator; total DMSOconcentration in both treated and control wells is adjusted to 1%. Cellsare then stimulated for 10 minutes with 100 nM IGF-1 added in 30 μlDMEM. After treatment, cells are lysed by addition of 30 μl of 4× lysisbuffer (phosphate-buffered saline (PBS), 2% Triton-X100, 1 mMphenylmethylsulphonyl fluoride (PMSF) and 8 mM activated orthovanadate),mixing and incubation for 15 minute at room temperature. To prepareassay plates, 96-well ELISA Plates (Pierce Chemical, Reacti-bind plates)were coated by goat-anti-rabbit Fc antiserum by adding 0.25 μg antiserumper well in 0.2M sodium bicarbonate buffer per well and incubatingovernight at 4° C. After incubation, the plate is washed three times byPBS with 0.02% Tween-20, supplied with 25 ng/50 μl per well ofanti-IGF1R antibody (C-20, Santa Cruz Biotechnology) and incubated forseveral hours to overnight. Prior to the addition of the preparedcellular lysates, the antibody solution is aspirated, wells washed withPBS and supplied with 25 μl per well of Starting Block buffer (PierceChemical).

To measure tyrosine phosphorylation of the beta-subunits of the IGF1R,25-50 μl of the lysates are transferred from the stimulation plate tothe wells of the prepared assay plate and incubated overnight at 4° C.The wells are washed with PBS with 0.02% Tween-20, incubated with 50 μlof 1:3000 dilution of anti-phosphotyrosine 4G10-HRP antibody conjugate(Upstate Biotechnology) for 2 hours at room temperature and washedagain. The assay plate was developed with Ultra TMB ELISA HRP substrate(Pierce Chemical) and absorbance of the wells was read at 450 nm inELISA plate reader. Alternatively, 10-50 times larger volumes of lysatesprepared as described above are incubated overnight at 4° C. with 1 μgof anti-IGF1R antibody (C-20; Santa Cruz Biotechnology) and 20 μl of 50%protein-A agarose slurry. After 3 washes with lysis buffer, pellets areresuspended in SDS-PAGE sample buffer and boiled for 3 minutes. Proteinsare resolved by SDS-PAGE (7.5%) and transferred by electroblotting ontonitrocellulose membranes. Tyrosine phosphorylated IGF1R is detected byimmunoblotting with anti-phosphotyrosine antibody (4G10, UpstateBiotechnology) and, in a separate identical blot, with anti-IGF1Rantibody. Table III below shows exemplary data for cellular receptorphosphorylation inhibition in terms of IC50 value.

The plated cells are mixed with the CellTiter-Glo developing reagent and counted in a luminescence multiwellplate reader according to the standard manufacturer's protocol togenerate IC50 curves for cell proliferation inhibition. Results aretypically reported as percent of growth (% viability=(OD_(72h(compound))−OD_(day0)))/(OD_(72h(no compound))−OD_(day0)).Alternatively, viable cells are quantitated by using the conventionalcolorimetric MTT assay. The MTT assay is based on the cleavage of theyellow tetrazolium salt MTT to purple formazan crystal by metabolicactive cells. The formazan is then solubilized, and the concentrationdetermined by optical density at 570 nm. The cells plated and incubatedwith a compound as described above are supplemented with the solution ofMTT and incubated for 2-3 hours. The growth medium is removed anddimethyl sulfoxide is added into each well to dissolve the formazan.
